Losing the Graphics on RedHat

[Margaret Doll]

The graphics on our system was working yesterday.

Today when the system was rebooted, one can see the details of the  
reboot including the Red screen showing the kernels installed on the  
system.  However, when the gnome login screen should appear, we are  
now only getting a dark blue screen.

We can run graphics programs across the network, but we cannot use our  
console.

We started the system up in single user mode, started all the daemons  
for a state 5
and then ran startx.

	avahi and hal fail.

	startx brings up the solid dark blue screen

	ddcprobe  does not find the monitor.

What should we try next?
